Flow Unit Converter


A flow unit converter is a tool used to convert between different units of flow, representing the volume of fluid passing through a particular point in a given time. Flow units are essential in various industries including fluid mechanics, engineering, environmental science, and manufacturing, where precise measurement and conversion of fluid flow rates are necessary for analysis and decision-making.

The flow rate (Q) can be calculated using the formula:

Q=VolumeTimeQ = \frac{Volume}{Time}


  • QQ = Flow rate (in the desired unit)
  • VolumeVolume = Volume of fluid passing through a point (in cubic meters, liters, gallons, etc.)
  • TimeTime = Time period over which the volume is measured (in seconds, hours, days, etc.)

How to Convert:

To convert between different units of flow, follow these steps:

  1. Identify the unit you have and the unit you want to convert to.
  2. Determine the conversion factor between the two units. This factor may involve simple multiplication or division.
  3. Multiply or divide the flow rate value by the conversion factor to obtain the equivalent value in the desired unit.


  1. Conversion from Cubic meter/second to Gallon (US)/minute:Conversion Factor: 1 cubic meter = 264.172 gallons (US), 1 second = 60 seconds1m3/s=264.172×601gal (US)/min1 \, \text{m}^3/\text{s} = \frac{264.172 \times 60}{1} \, \text{gal (US)/min}

  2. Conversion from Liter/hour to Cubic foot/second:Conversion Factor: 1 liter = 0.0353147 cubic feet, 1 hour = 3600 seconds1L/h=0.03531473600ft3/s1 \, \text{L/h} = \frac{0.0353147}{3600} \, \text{ft}^3/\text{s}

  3. Conversion from Pound/minute (Gasoline at 15.5°C) to Kilogram/second (Gasoline at 15.5°C):Conversion Factor: 1 pound = 0.453592 kilograms, 1 minute = 60 seconds1lb/min=0.45359260kg/s1 \, \text{lb/min} = \frac{0.453592}{60} \, \text{kg/s}

By following these steps, you can accurately convert between various units of flow, facilitating communication and analysis in applications where fluid dynamics play a crucial role.
